In order to clarify the mechanical properties of single-crystal silicon carbide (SiC), nanoindentation was performed on a 4H-SiC wafer. The change of hardness with the angle between the wafer orientation flat and the indenter edge, the maximum load and the loading rate were investigated. The hardness reached maximum at an indentation load of 12 mN in the range of 3-50 mN.

Silicon carbide has a Mohs hardness rating of 9, making it the hardest available material next to boron carbide (9.5) and diamond (10). It is this apparent property that makes SiC an excellent material choice for mechanical seals, bearings, and cutting tools. High-temperature resistance.
Until the invention of boron carbide in 1929, silicon carbide was the hardest synthetic material known. It has a Mohs hardness rating of 9, approaching that of diamond. In addition to hardness, silicon carbide crystals have fracture characteristics that make them extremely useful in grinding wheels and in abrasive paper and cloth products.

The extreme hardness of silicon carbideapproximately 9 on the Mohs scale, compared to 10 for diamondmakes Nye-Carb a wise choice for components that bear heavy loads in the absence of consistent lubriion. Few surfaces of any type can match the wear resistance of Nye-Carb™, a chemically applied silicon carbide coating that suspends
Mar 11, 2019· 6. Cubic silicon carbide, also known as Beta sic, is a cubic crystal system. The Beta sic hardness is 9.25--9.6, which is close to the diamond 10 and has a better finish than diamond. Beta sic is one of the hardest high-performance materials after steel. Its ultra-high hardness and density make it ideal for parts subject to high wear and
